Ok...I'm looking up LST stuff right now...

Regarding the lights -- that photo was taken after they'd been under the 400w lights for only a couple hours, prior to that they had a really weak fluro bulb that was actually only a couple inches away from their tops...could the stretching be from that fluro bulb not being strong enough, and if so, now that they have WAY more light, will they still be stretching too much?

The light is really hot, I'm worried about moving it too close...am I worried for nothing?
